FIELD

The subject matter disclosed herein relates to a dispensing unit withball functionality. More specifically, to a ball functionality thatallows for enhance fluid discharge.

INFORMATION

The dispensing industry has numerous ways to dispense one or more fluidsand/or gases. This disclosure highlights enhanced devices, methods, andsystems for dispensing these one or more fluids and/or gases.

Carbonated dispensing head valves commonly incorporate a “paddle valve”having an arm that activates the “open and close” function of the valve.The arm is required to penetrate through the chamber wall into theliquid chambers. This penetration creates a major failure point (i.e.leakage, sealing issues, etc.) of the existing units on the market.Additionally, with “wet” pistons in the solenoid a disadvantage occurswith the requirement that is has to be closely machined parallel to thesliding surfaces, as accuracy of the sliding surfaces is critical tomaintaining closing of the orifice. However, the lubricant for thesliding is typically the fluid that is being turned on and off. Thus, inmany cases the character of the fluid can have problems serving as alubricant. Lastly, as the piston is fixed, it is not self-cleaning. Itis to overcoming these problems with current paddle valves that thebelow disclosed novel valve is directed to.

DETAILED DESCRIPTION

Disclosed is a novel valve that does not require a shaft, piston, etc.or other component that is required to penetrated through the wall ofthe chamber where the liquid travels through (i.e. penetrates fromoutside the liquid to inside the chamber or wet side). With the belowdescribed valve, the necessity to penetrate into the wet side to actuatethe “on/off” for the valve is eliminated.

A ball or other substantially round or spherical object (collectively“Ball”) may be used and controlled by rolling the Ball off the openingto open the valve for fluid flow there through. This mechanism ofrolling the Ball off the opening is a mechanically easier process thanthe conventional lifting or diaphragm of the Ball in order to open thepassage/orifice.

With the disclosed rolling Ball valve, once the Ball is even partiallyoff the orifice/opening then the pressure will equalize on both sides ofthe orifice and the effort to move the Ball further off, farther tofully open, may take almost no energy at all. Once the Ball is decoupledfrom the magnet or the electro magnet is off—the fluid flow itself willroll [suck] the Ball back into the orifice and close the valve. Thehigher the input pressure the tighter the valve closes. In practice theorifice, as depicted, would be the most accommodating design for a valveseat as well (i.e. a self-cleaning rubber design) as used in theCFValves.

FIG. 1A and FIG. 1B illustrate a first embodiment for the valve in avalve closed position. FIG. 1A illustrates a top sectional view, whereasFIG. 1B illustrates a side sectional view for the first embodiment inthe closed position. As seen in these two Figures a Ball covers/closedan orifice opening, with a portion of the Ball extending into theorifice opening. With the Ball closing the orifice opening, fluid isprevented from flowing through the pipe, tube, chamber, hose or othertype if fluid conduit (all collectively referred to as “Conduit”). Asseen in FIG. 1B a magnetic coupling located on an external/outside ofthe Conduit is out of magnetic range of the metal Ball and thus isunable to control the movement or position of the Ball. The Ball istherefore forced in the shown sealing position with respect to theorifice opening by the pressure flow within the Conduit. Preferably, theBall is constructed from a magnetic, metallic and/or rigid material andall are considered within the scope of the disclosure.

FIG. 2A ad FIG. 2B illustrate a first embodiment for the valve in avalve open position. FIG. 2A illustrates a top sectional view, whereasFIG. 2B illustrates a side sectional view for the first embodiment inthe open position. As seen in these two Figures, the magnetic couplingis moved within magnetic range of the Ball, which causes the Ball topulled towards the externally located magnetic coupling and no longersealing the orifice opening, thus, allowing fluid flow through theorifice opening.

FIG. 3A ad FIG. 3B illustrate a second embodiment for the valve in avalve closed position. FIG. 3A illustrates a top sectional view, whereasFIG. 3B illustrates a side sectional view for the second embodiment in aclosed position. In this embodiment, the orifice opening is preferablynot centered. With the magnetic coupling out of magnetic range with theBall, the Ball is forced to seal the orifice opening by flow pressure.As seen in FIG. 4A and FIG. 4B when the magnetic coupling is rotated(e.g. 90 degrees, etc.), the magnetic coupling is now within magneticrange of the Ball, and thus pulls the Ball causing the orifice openingto be open and allow fluid flow there through.

FIG. 5A ad FIG. 5B illustrate a third embodiment for the valve in avalve closed position. FIG. 5A illustrates a top sectional view, whereasFIG. 5B illustrates a side sectional view for the third embodiment in aclosed position. In this embodiment, the orifice opening can bepreferably centered and an electro magnet provided which preferablyremains in a fixed position with respect to the Conduit. When theelectro magnet “off” (i.e. not energized), the Ball is forced to sealthe orifice opening by flow pressure. As seen in FIG. 6A and FIG. 6Bwhen the electro magnet is “on” (i.e. energized), the electro magnetpulls the Ball towards the electro magnet which causes the orificeopening to be open and allow fluid flow there through.

FIG. 7A and FIG. 7B illustrate a fourth embodiment for the valve in avalve closed position. FIG. 7A illustrates a top sectional view, whereasFIG. 7B illustrates a side sectional view for the third embodiment in aclosed position. In this embodiment, the orifice opening can bepreferably centered (however any spot can be utilized (e.g., right,center, left, slightly off center, 1 inch off center, etc.)) and amagnetic coil provided which preferably remains in a fixed position withrespect to the Conduit. When the electro magnet “off” (i.e. notenergized), the Ball is forced to seal the orifice opening by flowpressure. As seen in FIG. 8A and FIG. 8B when the magnetic coil is “on”(i.e. energized and creates a magnetic field), the Ball is pulledtowards the magnetic field which causes the orifice opening to be openand allow fluid flow there through.

Thus, in all embodiments, the movement of the Ball over the orificeopening and out of the orifice opening is achieved without having topenetrate the wall of the Conduit which eliminates or greatly reducesprevious leakage and other sealing problems, experienced at thepenetrate point and the other above-identified problems with priorvalves, such as, but not limited to “paddle valves”.

One non-limiting application for the above-described and shown novelvalve is in use with a beverage machine, such as, but not limited to,the multiple beverage dispensing machines found at restaurants where acustomer takes their cup and positions the cup under one of theplurality of beverage dispensing heads and presses the cup against alever to initiate dispensing. For this application, the magnet is movedor rotated by the a mechanical lever that is secured to, part of orotherwise in mechanical communication with the lever that the customerpresses their cup against to initiate dispensing. Here, when the levelis pressed by the customer, the magnet is moved or rotated such that itis in range with the Ball, thus, causing the Ball to be pulled out ofand/or away from the orifice, thus allowing the desired beverage to bedispensed out of the dispensing head above the customer's cup.

For the embodiments where the magnet is energized (as opposed to beingmoved or rotated) to pull the Ball away or out of the orifice, theelectrical source can be a 24 V AC, though such is not consideredlimiting. Here, when the customer presses their cup against the level,an electrical switch is turned “closed-on” (or “opened-off” depending onhow the circuit is wired), causing the energy from the electrical sourceto flow to the electro magnet or magnetic coil, thus, causing theelectro magnet or magnetic coil to pull and/or push the Ball out of oraway from the orifice.

As an alternative to the customer pushing their cup against a lever,certain beverage machines operate with the customer pushing a button toactivate an electrical circuit. Thus, this pressing of the button can besubstituted for pushing the cup against the lever in the abovenon-limiting examples. In either method (pushing cup against lever orpressing button), the objective is to stop or start a flow of fluidthrough the tube, pipe, etc. through the use of one of the abovedescribed Ball/orifice magnet embodiments.

Though not considered limiting, the magnet, electro magnet or magneticcoil can be attached or positioned adjacent to the Conduit by aconventional mechanical fastener, screws, bolts, etc., as well as glued,tape or other adhesive, incased in a plastic cover. Additionally, wherethe Conduit is plastic, a receptacle for the attachment—magnet, electromagnet or magnetic coil can be molded.

The disclosed embodiments are not considered limited to any particularmagnetic materials, orifice opening dimensions, orifice location, Balldimensions, Ball shape (e.g., circle, ball, square, triangle, etc.) Ballto orifice opening ratio, magnet location, electro magnet location ormagnetic coil location

All locations, sizes, shapes, measurements, ratios, amounts, angles,component or part locations, configurations, dimensions, values,materials, orientations, etc. discussed above or shown in the drawingsare merely by way of example and are not considered limiting and otherlocations, sizes, shapes, measurements, ratios, amounts, angles,component or part locations, configurations, dimensions, values,materials, orientations, etc. can be chosen and used and all areconsidered within the scope of the disclosure.

While the valve has been described and disclosed in certain terms andhas disclosed certain embodiments or modifications, persons skilled inthe art who have acquainted themselves with the disclosure, willappreciate that it is not necessarily limited by such terms, nor to thespecific embodiments and modification disclosed herein. Thus, a widevariety of alternatives, suggested by the teachings herein, can bepracticed without departing from the spirit of the disclosure, andrights to such alternatives are particularly reserved and consideredwithin the scope of the disclosure.

In FIG. 1A, an illustration of a ball functionality is shown, accordingto one embodiment. In one example, a dispensing element 200 may includea conduit 202, a blocking element 204, and a dispensing element 206(e.g., orifice). In various examples, the conduit 202 may be a hose, apipe, and/or any other element with an external surface and an internalsurface which allows for the passage of one or more fluids and/or one ormore gases. In various examples, the blocking element 204 may be a ball,a block, and/or any other element that stops the passage of one or morefluids and/or one or more gases when the blocking element is in one ormore positions relative to the dispensing element. In this example shownin FIG. 1A, the blocking element 204 is positioned over the dispensingelement 206 which stops the passage of one or more fluids and/or one ormore gases which can be seen in FIG. 1B. In the example shown in FIG.1B, the blocking element 204 stops a fluid flow because the flow (e.g.,line PSI) is putting pressure 208 on the blocking element 204 whichcreates a seal between the blocking element 204 and the dispensingelement 206 (the dispensing element 206 in this example is a hole and/orthe orifice opening(s)). In this example, the pressure 208 is all aroundthe blocking element but is strongest when it is parallel with thedispensing element. A movement device 220 (e.g., a magnet) is in a firstposition 220A which does not allow the movement device 220 to interactwith the blocking element 204.

In FIG. 2A, another illustration of a ball functionality is shown,according to one embodiment. In this example, the blocking element 204has moved to a second position relative to the dispensing element 206.In this example, the movement device 220 has moved to a second position220B which allows the movement device 220 to interact with the blockingelement as shown in FIG. 2B. The movement device 220 (e.g., a magnet)has caused the blocking element 204 (e.g., a Ferro-magnetic materialand/or a metal ball) to move in a first direction 210 towards themovement device 220 which allows for a first fluid flow 211 to movetowards the dispensing element 206 and a second fluid flow 222 throughthe dispensing element 206 until the movement device is moved back tothe first position 220A which causes the blocking element to move backto a position to block the flow of fluids through the dispensing element206 as shown in FIG. 1B. The movement device 220 in this example ismagnetically tied to the blocking element 204. Therefore, when themovement device 220 moves the blocking element 204 moves. It should benoted that there is a pressure difference (e.g., pressure differential)between the second area with the second fluid flow 222 and the firstarea with the first fluid flow 211.

In FIG. 3A, an illustration of a ball functionality is shown, accordingto one embodiment. In one example, a dispensing device 300 may include aconduit 202, a blocking element 204, and a dispensing element 206. Invarious examples, the conduit 202 may be a hose, a pipe, and/or anyother element with an external surface and an internal surface whichallows for the passage of one or more fluids and/or one or more gases.In various examples, the blocking element 204 may be a ball, a block, anegg shaped item, a tear drop shaped item, a golf tee shaped item, and/orany other shape. Further the blocking element 204 may be any otherelement that stops the passage of one or more fluids and/or one or moregases when the blocking element is in one or more positions relative tothe dispensing element. In this example shown in FIG. 3A, the blockingelement 204 is positioned over the dispensing element 206 which stopsthe passage of one or more fluids and/or one or more gases which can beseen in FIG. 3B. In the example shown in FIG. 3B, the blocking element204 stops a fluid flow because the flow (e.g., line PSI) is puttingpressure 208 on the blocking element 204 which creates a seal betweenthe blocking element 204 and the dispensing element 206 (the dispensingelement 206 in this example is a hole). A movement device (e.g., amagnet) is in a first position 304 which does not allow the movementdevice to interact with the blocking element 204.

In FIG. 4A, another illustration of a ball functionality is shown,according to one embodiment. In this example, the blocking element 204has moved to a second position relative to the dispensing element 206.In this example, the movement device has moved to a second position 302which allows the movement device to interact with the blocking elementas shown in FIG. 4B. The movement device (e.g., a magnet) has caused theblocking element 204 (e.g., a Ferro-magnetic material and/or a metalball) to move in a first direction 210 which allows for a first fluidflow 211 to move towards the dispensing element 206 and a second fluidflow 222 through the dispensing element 206 until the movement device ismoved back to the first position 304 which causes the blocking elementto move back to a position to block the flow of fluids through thedispensing element 206 as shown in FIG. 4B. In this example, themovement device is magnetically locked onto the blocking element 204.Therefore, when the movement device moves the blocking element 204moves.

In FIG. 5A, an illustration of a ball functionality is shown, accordingto one embodiment. In one example, a dispensing system may include theconduit 202, the blocking element 204, and the dispensing element 206.In various examples, the conduit 202 may be a hose, a pipe, and/or anyother element with an external surface and an internal surface whichallows for the passage of one or more fluids and/or one or more gases.In various examples, the blocking element 204 may be a ball, a block,and/or any other element that stops the passage of one or more fluidsand/or one or more gases when the blocking element is in one or morepositions relative to the dispensing element. In this example shown inFIG. 5A, the blocking element 204 is positioned over the dispensingelement 206 which stops the passage of one or more fluids and/or one ormore gases which can be seen in FIG. 5B. In the example shown in FIG.5B, the blocking element 204 stops a fluid flow because the flow (e.g.,line PSI) is putting pressure 208 on the blocking element 204 whichcreates a seal between the blocking element 204 and the dispensingelement 206 (the dispensing element 206 in this example is a hole orsealing ring). A movement device 500 (e.g., a magnet) is in a firststate (e.g., de-energized) which does not allow the movement device 500to interact with the blocking element 204.

In FIG. 6A, another illustration of a ball functionality is shown,according to one embodiment. In this example, the blocking element 204has moved to a second position relative to the dispensing element 206.In this example, the movement device 500 has been energized and is in asecond state 502 which allows the energized movement device 502 tointeract with the blocking element as shown in FIG. 6B. The energizedmovement device 502 (e.g., a magnet) has caused the blocking element 204(e.g., a Ferro-magnetic material and/or a metal ball) to move in a firstdirection 210 towards the energized movement device 502 which allows fora first fluid flow 211 to move towards the dispensing element 206 and asecond fluid flow 222 through the dispensing element 206 until theenergized movement device 502 returns in an de-energized movement device500 which causes the blocking element to move back to a position toblock the flow of fluids through the dispensing element 206 as shown inFIG. 6B.

In FIG. 7A, an illustration of a ball functionality is shown, accordingto one embodiment. In one example, a dispensing apparatus may includethe conduit 202, the blocking element 204, and the dispensing element206. In various examples, the conduit 202 may be a hose, a pipe, and/orany other element with an external surface and an internal surface whichallows for the passage of one or more fluids and/or one or more gases.In various examples, the blocking element 204 may be a ball, a block,and/or any other element that stops the passage of one or more fluidsand/or one or more gases when the blocking element is in one or morepositions relative to the dispensing element. In this example shown inFIG. 7A, the blocking element 204 is positioned over the dispensingelement 206 which stops the passage of one or more fluids and/or one ormore gases which can be seen in FIG. 7B. In the example shown in FIG.7B, the blocking element 204 stops a fluid flow because the flow (e.g.,line PSI) is putting pressure 208 on the blocking element 204 whichcreates a seal between the blocking element 204 and the dispensingelement 206 (the dispensing element 206 in this example is a hole). Amovement device 700 (e.g., a magnet) is in a first state (e.g.,de-energized) which does not allow the movement device 700 to interactwith the blocking element 204.

In FIG. 8A, another illustration of a ball functionality is shown,according to one embodiment. In this example, the blocking element 204has moved to a second position relative to the dispensing element 206.In this example, the movement device 700 has been energized and is in asecond state 702 which allows the energized movement device 702 tointeract with the blocking element as shown in FIG. 8B. The energizedmovement device 702 (e.g., a magnet) has caused the blocking element 204(e.g., a Ferro-magnetic material and/or a metal ball) to move in a firstdirection 704 towards the energized movement device 702 which allows fora first fluid flow 211 to move towards the dispensing element 206 and asecond fluid flow 222 through the dispensing element 206 until theenergized movement device 702 returns in an de-energized movement device700 which causes the blocking element to move back to a position toblock the flow of fluids through the dispensing element 206 as shown inFIG. 8B.

In FIG. 9A, another illustration of a ball functionality is shown,according to one embodiment. A dispensing device 902 may include aninlet area with a fluid flow 904 that comes into a first chamber. Thefirst chamber includes a blocking device 906 and a first chamber outletarea 908. Further, dispensing device 902 includes a dispensing deviceoutlet area 914. In this example, a magnet 900 is not energized whichallows the blocking device 906 to be in a first position relative to thefirst chamber outlet area 908 which prevents the fluid flow 904 fromexiting the first chamber outlet area 908. In FIG. 9B, the magnet 900 isenergized 910 which moves the blocking device 906 to a second positionrelative to the first chamber outlet area 908 and/or dispensing deviceoutlet area 914 which allows the fluid flow 904 to exit from the firstchamber outlet area 908 and creates a low pressure area 912.

In one example, the blocking device 906 becomes trapped in the lowpressure area 912 and/or a second low pressure area 920 as shown in FIG.9C. The magnet 900 may be energized 910 to remove the blocking devicefrom the low pressure area 912 and/or a second low pressure area 920 asshown in FIG. 9D.

FIG. 10A shows a dispensing apparatus 1006 with a metal ball 1008(and/or a Ferro-magnetic material—e.g., brass), a dispensing area 1010,and a magnetic coil 1002. In this example, the magnetic coil 1002 is notenergized which allows the metal ball 1008 to block the flow of liquidsand/or gases from escaping through the dispensing area 1010. However,once the magnetic coil 1002 is energized 1004, the metal ball 1008 moveto a second position which allows for the flow of liquids and/or gasesvia the dispensing area 1010.

FIG. 11A shows a dispensing system 1104 where a plastic covered metalball 1100 is utilized to block the flow of fluids and/or gases from adispensing unit 1102. In this example, once a magnet 1002 is energized,the plastic covered metal ball 1100 moves to a position that allows forthe flow of fluids and/or gases from a dispensing unit 1102 as shown inFIG. 11B.

In FIG. 12, an illustration of a dispensing unit with one or more ballfunctionalities is shown, according to one embodiment. A dispensingsystem 1200 may include a magnet 1202 (and/or any other movement deviceand/or initiating device) and one or more dispensing units 1208. In oneexample, when the magnet 1202 moves in a first direction 1204 one ormore of the one or more dispensing units 1208 may discharge one or morefluids and/or gases. In one example, when the magnet 1202 moves in asecond direction 1206 one or more of the one or more dispensing units1208 may discharge one or more fluids and/or gases. In a first example,an orange flavored drink may be dispensed when the magnet 1202 comesinto a first relative position to a first dispensing unit. In a secondexample, a cherry flavored drink may be dispensed when the magnet 1202comes into a second relative position to a second dispensing unit. In athird example, a cola flavored drink may be dispensed when the magnet1202 comes into a third relative position to a third dispensing unit. Ina fourth example, a lemon flavored drink may be dispensed when themagnet 1202 comes into a fourth relative position to a fourth dispensingunit. In an Nth example, a peach flavored drink may be dispensed whenthe magnet 1202 comes into an Nth relative position to an Nth dispensingunit.

In FIG. 13A, another illustration of a dispensing unit with one or moreball functionalities is shown, according to one embodiment. A dispensingsystem may include a magnet 1300 (and/or any other movement deviceand/or initiating device) and one or more dispensing units (a firstdispensing unit 1302, a second dispensing unit 1304, a third dispensingunit 1306, a fourth dispensing unit 1308, an Nth−1 dispensing unit 1310,and an Nth dispensing unit 1312. In a first example, an orange flavoreddrink may be dispensed when the magnet 1300 comes into a first relativeposition to a first dispensing unit 1302 by moving a blocking element1314. In a second example, a cherry flavored drink may be dispensed whenthe magnet 1300 comes into a second relative position to a seconddispensing unit 1304 by moving a blocking element 1314. In a thirdexample, a cola flavored drink may be dispensed when the magnet 1300comes into a third relative position to a third dispensing unit 1306 bymoving a blocking element 1314. In a fourth example, a lemon flavoreddrink may be dispensed when the magnet 1300 comes into a fourth relativeposition to a fourth dispensing unit 1308 by moving a blocking element1314. In an Nth−1 example, a black cherry flavored drink may bedispensed when the magnet 1300 comes into an Nth−1 relative position toan Nth−1 dispensing unit 1310 by moving a blocking element 1314. In anNth example, a peach flavored drink may be dispensed when the magnet1300 comes into an Nth relative position to an Nth dispensing unit 1312by moving a blocking element 1314.

In FIG. 13B, another illustration of a dispensing unit with one or moreball functionalities is shown, according to one embodiment. In thisexample, a dispensing apparatus 1350 includes one or more dispensingunits 1354 and a currently selected dispensing unit 1360. The currentlyselected dispensing unit 1360 dispenses one or more drinks via atriggering unit 1356 with a triggering mechanism 1358. In this example,the one or more dispensing units 1354 and/or the triggering unit 1356and/or the triggering mechanism 1358 may move in any direction 1352.

In FIG. 14, an illustration of a dispensing unit with one or more ballfunctionalities is shown, according to one embodiment. A dispensingsystem 1400 may include a dispensing unit 1402. The dispensing unit 1402may include a dispensing head 1404, an input device 1406 with an inputreceiving area 1408 and magnetic area 1410, a drink unit 1418 with ablocking element 1416, and a feed line 1414. Further, the input device1406 may have a spring support 1412. In one example, when a person wantsa drink that person pushes their cup on the input receiving area 1408which moves the input device 1406 towards the drink unit 1418. After theinput device 1406 (and the magnetic area 1410) come in proximate to thedrink unit 1418 (and the blocking element 1416) flow of the fluid isinitiated based on the magnetic area 1410 moving the blocking element1416. Once the person stops pushing the input device 1406, the magneticarea 1410 moves away from the blocking element 1416 and the flow offluids is stopped by the blocking element 1416.

FIG. 15A shows a top view of a dispensing unit 1500 including an outersurface 1502, an inner surface 1506, one or more locations for a drinkunit 1508, and a magnetic area 1504. FIG. 15B shows a side view of thedispensing unit 1500. FIG. 15C shows another view of the dispensing unit1500.

In FIG. 16A, another illustration of a dispensing unit with one or moreball functionalities is shown, according to one embodiment. A dispensingsystem 1600 may one or more dispensing devices 1602, a magnet 1610(and/or any other movement device and/or initiating device) and one ormore dispensing units (a first dispensing unit 1606, a second dispensingunit 1604, a third dispensing unit, a fourth dispensing unit, an Nth−1dispensing unit, and an Nth dispensing unit 1608. In a first example, anorange flavored drink may be dispensed when the magnet 1610 comes(and/or is energized) into a first relative position to a firstdispensing unit 1606 by moving a blocking element which allows for afluid flow 1612. In a second example, a cherry flavored drink may bedispensed when the magnet 1610 comes (and/or is energized) into a secondrelative position to a second dispensing unit 1604 by moving a blockingelement which allows for the fluid flow 1612. In a third example, a colaflavored drink may be dispensed when the magnet 1610 comes (and/or isenergized) into a third relative position to a third dispensing unit bymoving a blocking element which allows for the fluid flow 1612. In afourth example, a lemon flavored drink may be dispensed when the magnet1610 comes (and/or is energized) into a fourth relative position to afourth dispensing unit by moving a blocking element which allows for thefluid flow 1612. In an Nth example, a peach flavored drink may bedispensed when the magnet 1610 comes (and/or is energized) into an Nthrelative position to an Nth dispensing unit 1608 by moving a blockingelement which allows for the fluid to flow. In another example shown inFIG. 16B, a carbonated water unit 1614 may be utilized which allows fora carbonated flow 1616.

In FIG. 17, a flow diagram of a ball functionality is shown, accordingto one embodiment. A method 1700 may include having a check ball (e.g.,blocking element, blockage device, etc.) in a blocking position to blocka fluid flow based on a magnet being in a first position (step 1702).The method 1700 may include moving the magnet to a second position (step1704). The method 1700 may include having the check ball in anunblocking positon which allows fluid flow (and/or gaseous flow) basedon the magnet being in a second position (step 1706).

In one example, the blocking element 204 is positioned over thedispensing element 206 which stops the passage of one or more fluidsand/or one or more gases which can be seen in FIG. 1B. In the exampleshown in FIG. 1B, the blocking element 204 stops a fluid flow becausethe flow (e.g., line PSI) is putting pressure 208 on the blockingelement 204 which creates a seal between the blocking element 204 andthe dispensing element 206 (the dispensing element 206 in this exampleis a hole). A movement device 220 (e.g., a magnet) is in a firstposition 220A which does not allow the movement device 220 to interactwith the blocking element 204.

Further, the blocking element 204 has moved to a second positionrelative to the dispensing element 206. In this example, the movementdevice 220 has moved to a second position 220B which allows the movementdevice 220 to interact with the blocking element as shown in FIG. 2B.The movement device 220 (e.g., a magnet) has caused the blocking element204 (e.g., a Ferro-magnetic material and/or a metal ball) to move in afirst direction 210 towards the movement device 220 which allows for afirst fluid flow 211 to move towards the dispensing element 206 and asecond fluid flow 222 through the dispensing element 206 until themovement device is moved back to the first position 220A which causesthe blocking element to move back to a position to block the flow offluids through the dispensing element 206 as shown in FIG. 1B.

In FIG. 18, a flow diagram of a ball functionality is shown, accordingto one embodiment. A method 1800 may include having a check ball (e.g.,blocking element, blockage device, etc.) in a blocking position to blockfluid flow based on the magnet being off (e.g., de-energized) (step1802). The method 1800 may include turning the magnet on (e.g.,energizing) (step 1804). The method 1800 may include having the checkball in an unblocking position based on the magnet being on (step 1806).

In one example, the blocking element 204 is positioned over thedispensing element 206 which stops the passage of one or more fluidsand/or one or more gases which can be seen in FIG. 5B. In the exampleshown in FIG. 5B, the blocking element 204 stops a fluid flow becausethe flow (e.g., line PSI) is putting pressure 208 on the blockingelement 204 which creates a seal between the blocking element 204 andthe dispensing element 206 (the dispensing element 206 in this exampleis a hole). A movement device 500 (e.g., a magnet) is in a first state(e.g., de-energized) which does not allow the movement device 500 tointeract with the blocking element 204.

Further, the blocking element 204 has moved to a second positionrelative to the dispensing element 206. In this example, the movementdevice 500 has been energized and is in a second state 502 which allowsthe energized movement device 502 to interact with the blocking elementas shown in FIG. 6B. The energized movement device 502 (e.g., a magnet)has caused the blocking element 204 (e.g., a Ferro-magnetic materialand/or a metal ball) to move in a first direction 210 towards theenergized movement device 502 which allows for a first fluid flow 211 tomove towards the dispensing element 206 and a second fluid flow 222through the dispensing element 206 until the energized movement device502 returns in an de-energized movement device 500 which causes theblocking element to move back to a position to block the flow of fluidsthrough the dispensing element 206 as shown in FIG. 6B.

In another example, the blocking element 204 is positioned over thedispensing element 206 which stops the passage of one or more fluidsand/or one or more gases which can be seen in FIG. 7B. In the exampleshown in FIG. 7B, the blocking element 204 stops a fluid flow becausethe flow (e.g., line PSI) is putting pressure 208 on the blockingelement 204 which creates a seal between the blocking element 204 andthe dispensing element 206 (the dispensing element 206 in this exampleis a hole). A movement device 700 (e.g., a magnet) is in a first state(e.g., de-energized) which does not allow the movement device 700 tointeract with the blocking element 204.

Further, the blocking element 204 has moved to a second positionrelative to the dispensing element 206. In this example, the movementdevice 700 has been energized and is in a second state 702 which allowsthe energized movement device 702 to interact with the blocking elementas shown in FIG. 8B. The energized movement device 702 (e.g., a magnet)has caused the blocking element 204 (e.g., a Ferro-magnetic materialand/or a metal ball) to move in a first direction 704 towards theenergized movement device 702 which allows for a first fluid flow 211 tomove towards the dispensing element 206 and a second fluid flow 222through the dispensing element 206 until the energized movement device502 returns in an de-energized movement device 700 which causes theblocking element to move back to a position to block the flow of fluidsthrough the dispensing element 206 as shown in FIG. 8B.

In FIG. 19, a flow diagram of a ball functionality is shown, accordingto one embodiment. A method 1900 may include having one or more checkballs (e.g., blocking element, blockage device, etc.) in one or moredispensing units which have one or more flavors in a non-flow position(step 1902). The method 1900 may include moving an initiating flowdevice towards one dispensing unit (step 1904). The method 1900 mayinclude initiating flow on one dispensing unit based on the initiatingdevice moving the check ball (step 1906). In one example, when a personwants a drink that person pushes their cup on the input receiving area1408 which moves the input device 1406 towards the drink unit 1418.After the input device 1406 (and the magnetic area 1410) come inproximate to the drink unit 1418 (and the blocking element 1416) flow ofthe fluid is initiated based on the magnetic area 1410 moving theblocking element 1416. Once the person stops pushing the input device1406, the magnetic area 1410 moves away from the blocking element 1416and the flow of fluids is stopped by the blocking element 1416.

In FIG. 20, a regulating valve includes an outer housing comprised of acap joined to a base. The housing is internally subdivided by a barrierwall into a head section and a base section, the latter being furthersubdivided by a modulating assembly into a fluid chamber and a springchamber. An inlet and a 90° outlet (please note outlet angle may be anyangle from 0 to 360 degrees) in the cap communicate with the fluidchamber. Fluid at a variable pressure is admitted into the fluid chambervia the inlet, with the modulating assembly serving to maintain thefluid exiting the fluid chamber via the outlet at a substantiallyconstant pressure.

This disclosure relates generally to fluid valves, and is concerned inparticular with a regulating valve that is normally closed, that isopened by a variable fluid pressure above a selected threshold level,and that when open, serves to deliver the fluid at a constant pressureand flow rate

The drawing in FIG. 20 is a sectional view through a regulating valve inaccordance with the present disclosure, the valve being shown is in itsopen condition.

With reference to the drawing, a regulating valve in accordance with thepresent disclosure is generally depicted at 2010. The valve includes anouter housing having a cap 2012 joined to a cup-shaped base 2014 atmating exterior flanges 2016, 2018, with an O-ring seal 2020 interposedthere between.

The housing is internally subdivided by a barrier wall 2022 into a headsection 2024 and a base section 2026. An inlet 2028 in the cap 2012 isadapted to be connected to a fluid supply (not shown) having a pressurethat can vary from below to above a threshold level. The inlet 2028 anda central port 2030 in the barrier wall 2022 are aligned along a centralaxis A1 of the valve. An outlet port 2031, also in the cap 2012, isaligned on a second axis A2 transverse to the first axis A1.

A modulating assembly 2032 cooperates with the barrier wall 2022 tosubdivide the base section into a fluid chamber 2031 segregated from aspring chamber 2023″. The modulating assembly serves to prevent fluidflow through the valve when the fluid pressure at the inlet 2028 isbelow the threshold pressure.

When the fluid pressure at the inlet exceeds the threshold pressure, themodulating assembly serves to accommodate fluid flow from the headsection 2024 through port 2030 into chamber 2023′ at a constant pressureand flow rate, and from there through outlet port 2031. Either theoutlet port 2031 or a downstream orifice or flow restrictor (not shown)serves to develop a back pressure in fluid chamber 2023′.

The modulating assembly 2032 includes a piston comprised of a hollowshell 2034 and a central plug 2036. The piston is supported for movementin opposite directions along axis A1 by a flexible annular diaphragm2038. The inner periphery of the diaphragm is captured between the shell2034 and plug 2036. The cup shaped base 2014 has a cylindrical wallsegment 2014′ received within the cap 2012. The outer periphery of thediaphragm is captured between an upper rim 2015 of the wall segment2014′ and an inwardly projecting interior ledge 2017 on the cap.

A stem 2040 on the piston plug 2036 projects through the port 2030 intothe head section 2024. An enlarged head 2042 on the stem has a taperedunderside 2044 that coacts with a tapered surface 2046 of the barrierwall to modulate the size of the flow path through the port 2030 as aninverse function of the varying fluid pressure in the input section,with the result being to deliver fluid to the outlet 2031 at a constantpressure and flow rate.

A compression spring 2048 in the spring chamber 2023″ is capturedbetween an underside surface of shell 2034 and the bottom wall 2052 ofthe housing base 2014. The spring urges the modulating assembly 2032towards the barrier wall 2022. When the fluid pressure at the inlet 2028is below the threshold pressure, spring 2048 serves to urge thediaphragm 2038 against the barrier wall 2022, thus preventing fluid flowfrom the fluid chamber 2023′ to the outlet 2031′. As the fluid pressureexceeds the threshold pressure, the resilient closure force of spring2048 is overcome, allowing the piston assembly to move away from thebarrier wall, and allowing the modulating function of the coactingtapered surfaces 2044, 2046 to commence. An opening 2050 in the bottomwall 2052 serves to vent the volume beneath diaphragm 2038 to thesurrounding atmosphere.

In one example, a regulating valve for receiving fluid at a variablepressure from a fluid source and for delivering the fluid at asubstantially constant pressure and flow rate to a fluid applicator orthe like, the valve including: a cup-shaped base having a cylindricalwall segment terminating in an upper rim, and an externally projectingfirst flange; a cap having an inwardly projecting ledge and anexternally projecting second flange, the cup-shaped base and the capbeing configured and dimensioned for assembly as a unitary housing, withthe cylindrical wall segment of the cup-shaped base inserted into thecap, and with the extent of such insertion being limited by the abutmentof the first flange with the second flange to thereby provide a spacebetween the upper rim of the cup-shaped base and the inwardly projectingledge of the cap; a barrier wall subdividing the interior of the housinginto a head section and a base section; a modulating assemblysubdividing the base section into a fluid chamber and a spring chamber;an inlet in the cap for connecting the head section to the fluid source;a port in the barrier wall connecting the head section to the fluidchamber, the port being aligned with a central first axis of the valve;an outlet in the cap communicating with the fluid chamber, the outletbeing aligned on a second axis transverse to the first axis; a stemprojecting from the modulating assembly along the first axis through theport into the head section; a flexible diaphragm supporting themodulating assembly within the housing for movement in oppositedirections along the first axis, the diaphragm having an outer peripherycaptured in the space between the inwardly projecting ledge of the capand a rim of the cylindrical wall segment of the cup-shaped base; aspring in the spring chamber, the spring being arranged to resilientlyurge the modulating assembly into a closed position at which thediaphragm is in sealing contact with the barrier wall to thereby preventfluid flow from the head section via the port and fluid chamber to theoutlet, the spring acting in concert with the modulating assembly andthe stem projecting therefrom to modulate the size of the port as aninverse function of the variable fluid pressure in the input sectionswhereby the pressure and flow rate of the fluid delivered to the outletis maintained substantially constant, the valve being automaticallyactuated when the pressure of the fluid acting on the modulatingassembly exceeds a threshold level, and being automatically closed whenthe pressure drops below the threshold level.

In FIG. 21, a magnetically activated ball valve device 2100 has beenadded to regulating valve 2010 where the magnetically activated ballvalve device 2100 is located in a position relative to the inlet (e.g.,incoming fluid). In this example, the magnetically activated ball valvedevice 2100 includes an opening 2106, a ball 2102, and a magnetic device2104. Additional embodiments of the magnetically activated ball valvedevice 2100 and the functionality of the magnetically activated ballvalve device 2100 are shown in other figures of this disclosure. Inother embodiments, the ball valve device 2100 may be activated by thefluid flow, mechanical functionality (e.g., levers, etc.), magneticfunctionality, and/or any combination of movement devices.

In FIG. 22, a magnetically activated ball valve device 2202 has beenadded to regulating valve 2028 where the magnetically activated ballvalve device 2202 is located in a position relative to the outlet (e.g.,outgoing fluid). In this example, the magnetically activated ball valvedevice 2202 includes an opening 2200, a ball 2204, and a magnetic device2206. Additional embodiments of the magnetically activated ball valvedevice 2202 and the functionality of the magnetically activated ballvalve device 2202 are shown in the other figures of this disclosure.

A constant flow regulating valve includes a closure mechanism configuredand arranged to override the modulating mode of the valve and to closethe valve at fluid inlet pressures both below and above the valve'sthreshold level. The closure mechanism may be selectively deactivated tothereby allow the valve to assume its normal pressure responsiveregulating functions. Embodiments of the regulating valve incorporatepressure relief devices and vent seals, with configurations suitable forincorporation into the trigger assemblies of portable sprayers.

This disclosure relates generally to fluid valves, and is concerned inparticular with a regulating valve that operates in response to avariable fluid inlet pressure above a selected threshold level todeliver the fluid at a constant outlet pressure and flow rate. A closuremechanism is selectively operable either to accommodate the valve'snormal pressure responsive regulating functions, or to override suchfunctions by maintaining the valve in a closed state at inlet pressuresboth above and below the threshold level.

In one example, valves are normally closed in response to fluid inletpressures below a threshold level, and operate in a modulating mode inresponse to variable fluid inlet pressures above the threshold level todeliver fluids at constant outlet pressures and flow rates. However, atfluid inlet pressures above the threshold level, such valves remain openand cannot serve as shut off valves, thus making it necessary to employadditional and separately operable valves to achieve this addedfunction.

In accordance with one aspect of the present disclosure, the knownregulating valves are modified to include closure mechanisms configuredand arranged to override the modulating mode of the valves and tomaintain closure of the valves at fluid inlet pressures both below andabove the threshold level. The closure mechanisms may be selectivelydeactivated to thereby allow the valves to assume their normal pressureresponsive regulating functions.

In accordance with still another aspect of the present disclosure, thevent opening communicating with the valve's spring chamber is providedwith a seal which allows air to escape and enter the spring chamber, butwhich prevents the escape of liquid from the spring chamber in the eventthat the valve diaphragm is breached.

In accordance with another aspect of the present disclosure, a pressurerelief mechanism is provided for relieving residual fluid inlet pressurebelow the threshold level when the valve is closed.

In accordance with another aspect of the present disclosure, multiplevalve components are preassembled into integral subassemblies that areconfigured and arranged for final assembly into an outer housingstructure.

In accordance with a further aspect of the present disclosure, the valveis integrated into the trigger assembly of a portable sprayer.

With reference initially to FIG. 23, a regulating valve in accordancewith the present disclosure is generally depicted at 2010. The valveincludes an outer housing having a cap 2012 joined to a cup-shaped base2014 at mating exterior flanges 2016, 2018.

The housing is internally subdivided by a barrier wall 2022 into a headsection 2024 and a base section 2026. An inlet 2028 in the cap 2012 isadapted to be connected to a fluid supply (not shown) having a pressurethat can vary from below to above a threshold level. The inlet 2028 anda central port 2030 in the barrier wall 2022 are preferably alignedcoaxially with a central axis A1 of the valve. An outlet port 2031 isprovided in the cap 2012, and may be aligned on a second axis A2transverse to the first axis A1. Although the axis A2 is shown at 90°with respect to axis A1, it will be understood that axis A2 may beoriented at other angles with respect to axis A1 in order to suitvarious applications of the valve.

A modulating assembly 2032 internally subdivides the base section into afluid chamber 2023′ segregated from a spring chamber 2023″. Themodulating assembly serves to prevent fluid flow through the valve whenthe fluid pressure at the inlet 2028 is below the threshold pressure.When the fluid pressure at the inlet exceeds the threshold pressure, themodulating assembly serves to accommodate fluid flow from the headsection 2024 through port 2030 into fluid chamber 2023′ and from therethrough outlet port 2031 at a substantially constant outlet pressure andflow rate. Either the outlet port 2031 or a downstream orifice or flowrestrictor (not shown) serves to develop a back pressure in fluidchamber 2023′.

The modulating assembly 2032 includes a piston comprised of a hollowshell 2034 and a central plug 2036. The piston is supported for movementin opposite directions along axis A1 by a flexible annular diaphragm2038. The inner periphery of the diaphragm is captured between the shell2034 and plug 2036. The cup shaped base 2014 has a cylindrical wallsegment 2014′ received within the cap 2012. The outer periphery of thediaphragm is captured between an upper rim 2015 of the wall segment2014′ and an inwardly projecting interior ledge 2017 on the cap. Theouter periphery of the diaphragm thus serves as an effective sealbetween the cap 2012 and base 2014.

A stem 2040 on the piston plug 2036 projects through the port 2030 intothe head section 2024. An enlarged head 2042 on the stem has a taperedunderside 2044 that coacts with a tapered surface 2046 of the barrierwall to modulate the size of the flow path through the port 2030 as aninverse function of the varying fluid pressure in the input section,with the result being to deliver fluid to the outlet 2031 at asubstantially constant pressure and flow rate.

A compression spring 2048 in the spring chamber 2023″ is capturedbetween an underside surface of shell 2034 and the bottom wall 2052 ofthe housing base 2014. The spring urges the modulating assembly 2032towards the barrier wall 2022. When the fluid inlet pressure is belowthe threshold pressure, spring 2048 serves to urge the diaphragm 2038against a sealing ring 2049 on the underside of the barrier wall 2022,thus preventing fluid through flow from the head section 2024 via port2030 and fluid chamber 2023′ to the outlet 2031. As the fluid inletpressure exceeds the threshold pressure, the resilient closure force ofspring 2048 is overcome, allowing the modulating assembly to move awayfrom the sealing ring 2049, and allowing the modulating function of thecoacting tapered surfaces 2044, 2046 to commence. An opening 2050 in thebottom wall 2052 serves to vent the volume beneath diaphragm 2038 to thesurrounding atmosphere.

An operating means includes a solenoid 2054 fitted to the underside ofthe cup-shaped base 2014. The solenoid includes a magnet 2056surrounding a magnet core 2058. A rod 2060 projects from the magnet corealong axis A1 into the spring chamber 2023″ where it terminates in aflat head 2062. A closure means includes a second compression spring2064 surrounding the rod 2060 and captured between the head 2062 and anannular interior boss 2066 on the bottom wall 2052 of the base 2014. Theclosure force of spring 2064 exceeds that of spring 2048.

In the condition shown in the drawing, the magnet 2056 has beenenergized to axially withdraw the core 2058, thus pulling the head 2062downwardly against the compressive force of spring 2064 and away fromthe underside of plug 2034. This allows the modulating assembly 2032 toperform its normal pressure regulating functions as described above.

If the magnet 2056 is de-energized, the spring 2064 will serve to pushthe head 2062 up against the bottom of plug 2034 with a closure forcesufficient to override the valve's normal regulating functions,resulting in the diaphragm assembly 2032 being elevated to press thediaphragm 2038 against the circular downwardly projecting sealing ring2049 on the barrier wall 2022. This in turn prevents fluid through flowfrom head section 2024 via port 2030 and fluid chamber 2023′ to theoutlet port 2031. A circular ledge 2070 serves as a stop to limit upwardmovement of the core 2058, thus safeguarding the diaphragm 2038 frombeing pressed too tightly against the sealing ring 2049. The closureforce of spring 2064 is sufficient to hold the diaphragm 2038 againstthe sealing ring 2049 at inlet pressures above the threshold pressure.

In the alternative embodiment shown in FIG. 24, the rod 2060′ projectsthrough the bottom wall 2052 to terminate in a foot 2063 acted upon by alever 2068 mounted for pivotal movement about a pin 2069 or the like.Moving the lever up causes the rod 2060′ to be pulled downwardly.

In light of the foregoing, it will be seen that the valve 2010 can serveas a shut off valve by simply allowing the spring 2064 to overridespring 2048 and maintain the diaphragm 2038 of the modulating assembly2032 in sealing contact with the ring 2049 on barrier wall 2022. Bydeactivating the closure force of spring 2064, either by energizing thesolenoid 2054 of FIG. 23 or manually operating lever 2068 of FIG. 24,the valve is conditioned to assume its normal pressure responsiveregulating function at inlet pressures above the threshold level.

As can be best seen by additional reference to FIGS. 25 and 26, a gaspermeable hydrophobic seal 72 overlies the vent opening 50. The seal maycomprise an expanded polytetraflouroethelene (ePTFE) film, or any othergas permeable hydrophobic membrane that allows air to escape from andreenter the spring chamber 23″, but that in event of failure of thediaphragm 38 and entry of liquid into the spring chamber, will preventliquid from leaking to the exterior of the valve via the vent opening50. The seal 72 may be adhered or heat sealed to the bottom wall 52 asat 74. Although not shown, the seal may be reinforced, if necessary, byan additional porous membrane, e.g., a woven fabric or the like.

FIG. 27 depicts an alternative embodiment of the vent seal in which abushing 76 has been snap fitted into the vent opening 50. The bushing ismolded of a hydrophilic polymer that absorbs water and swells, resultingin closure of the restricted central vent passageway 78. This againserves to prevent leakage in the event of failure of the diaphragm 38.

FIG. 28 depicts still another alternative embodiment of the vent seal inwhich the vent opening 50 is located at the center of bottom wall 52. Aflexible sealing diaphragm 80 of some material that is impervious toboth liquids and air is adhered or heat sealed as at 82 over the ventopening. As air pressure in the spring chamber 23″ varies in response toflexure of the main diaphragm 38, the sealing diaphragm 80 will respondflexibly, while at all times maintaining a sealing relationship whichwill prevent liquid from escaping through the vent opening.

It thus will be seen that the seals 72, 76 and 80 serve as safeguardsagainst leakage of liquid from the regulating valve through vent openingso in the event that the diaphragm 38 is breached.

The regulating valves of the present disclosure are adaptable towidespread usage, a non-limiting example being to stabilize the pressureand flow of the liquid sprays emitted by portable sprayers.

Portable sprayers include both knapsack sprayers and compressionsprayers. In the conventional knapsack sprayer, a lever actuated pump ismanually operated to withdraw liquid from a non-pressurized portabletank and to deliver the liquid through a wand to a nozzle from which theliquid is expelled in a spray pattern. In a compression sprayer, thetank is pressurized to achieve the same result. In both cases, thedelivery pressure varies over a wide range, which affects the liquidspray pattern. Too little pressure produces excessively large wastefulspray droplets, whereas excessive pressure operates in the reversemanner to produce an overly atomized spray which can easily drift fromthe intended target.

Some attempt at control is provided by manually operating triggerassemblies interposed in the flow path between the tank and nozzle.However, experience has proven that operators are unable to operate suchtrigger assemblies in a manner which reliably produces substantiallyuniform delivery pressures and liquid flow rates to the spray nozzles.Thus, spray patterns remain erratic; resulting in wasteful excessiveliquid application and/or inadequate overly atomized sprays which oftendrift dangerously from their intended targets.

In order to address these problems, and with reference to FIGS. 30-32, aknapsack sprayer 84 includes a tank 86 adapted to contain a liquid,typically a pesticide, herbicide or the like. A pump 88 is mountedwithin the tank, with an inlet submerged in the liquid, and an outletconnected to a flexible hose 90 leading to trigger assembly 94incorporating a selectively actuated regulating valve in accordance withthe present disclosure. The trigger assembly 94 is in turn connected toa wand 92 having a nozzle 95 at its distal end. The pump 88 is operatedby a pivotal lever 96 which is manually manipulated by an operator towithdraw liquid from the tank 86 and to deliver the liquid at a variablepressure via the hose 90 to the trigger assembly 94. Although not shown,it will be understood that the pressurized tank of a compression sprayerwould operate in a similar manner to deliver fluid at a variablepressure.

The trigger assembly 94 incorporates a regulating valve similar to thatillustrated in FIG. 24, with minor modifications to accommodate itspositioning in the liquid flow path between the hose 90 and wand 92. Forexample, the head section 24 has been reconfigured with a 90° turn toposition the inlet 28 for connection to the hose 90, the shape andpivotal connection of the operating lever 68 has been appropriatelymodified to serve as the trigger, and the outlet port has been connectedto the wand 92.

The regulating valve of the trigger assembly 94 is held closed by theforce of spring 64. The closure force of spring 64 is relieved bydepressing the trigger 68, and in response to pump pressures above thepreset threshold level, the valve operates as described previously tomaintain a substantially constant delivery pressure and flow rate viathe wand 92 to the nozzle 95. By maintaining a substantially constantpressure and flow rate to the nozzle 95, the selected spray patternremains stable irrespective of variations in the pressure and flow rateof the liquid exiting tank 86.

The regulating valve of the trigger assembly 94 may be additionallymodified to include pressure relief means for relieving residualinternal pressures in the head section 24 when the valve is closed andeither disassembly is required for cleaning and maintenance, or when thetrigger assembly is disconnected from the hose 90. To this end, a sleeve98 is inserted in the cap 12. The sleeve provides a vent path 100extending from an entry opening communicating with the head section 24to a side exit opening 102 communicating with the fluid chamber 23′. Apin 104 extends through the sleeve and terminates at opposite ends inenlarged shaped closure and operating heads 106, 108 locatedrespectively in head section 24 and at the valve exterior. A spring 110serves to bias the pin to the right as viewed in the drawings, thuspulling the closure head 106 in the same direction to close off the ventpath 100, as shown in FIG. 31. The vent path is opened by depressingoperating head 108 to shift pin in the opposite direction, as shown inFIG. 32, thus opening the vent path and allowing pressurized liquid inthe head section 24 to be bled through opening 102 to the fluid chamber23′ from which it can exit through outlet port 31 to the wand 92.

With reference additionally to FIGS. 32-34, another embodiment of aregulating valve is accordance with the present disclosure is depictedat 94 a. The components of valve 94 a that are the same or equivalent tothose of value 94 depicted in FIG. 30 have been identified with the samereference numerals with “a” as an added identify.

A compressible annular seal 130 is then inserted via opening 112 andlocated against the bottom of the diaphragm 38 a.

The second subassembly 128 is then inserted through bottom opening 112.As shown in FIG. 31, the interior wall of the cap 12 is provided withoppositely disposed vertical grooves 132 leading to horizontal grooves134. The grooves 134 have ramped bottoms 136 leading to notches 138. Thecup-shaped base 14 has an oppositely disposed radially projecting ears140.

As the second subassembly 128 is inserted, the ears 140 of thecup-shaped base 14 a enter the vertical slots 132 (FIG. 35A). When aninternal ledge 141 adjacent to the upper rim of the cup-shaped base 14 ainitially contacts the seal 130, the ears 140 are positioned as shown inFIG. 35B. The cup-shaped base is then rotated to shift the ears up theramped bottoms 136 and into snapped engagement in the notches 136, asshown in FIG. 35C. The second subassembly is then securely locked inplace, with the seal 130 compressed between the underside of thediaphragm 38 a and the ledge 141.

The trigger 68 may then be operatively connected to the cap 12 a and rod60 a′ to complete the assembly.

It will be understood that the second subassembly 128 may be secured inplace by other means, including for example solvent welding or athreaded connection. Preassembly of the first and second subassembliesadvantageously simplifies final assembly of the regulating valves.
